Title: Protecting device for motor driver
Inventor: OKURA MITSUGI
IPC: H02P29/00
Filed: 1989-07-06
Abstract: PURPOSE:To suitably protect a motor by detecting a power source voltage, obtaining a voltage level to be converted from the detected voltage level, and continuing the operation of the motor even if the power source voltage level is lowered when the voltage level to be converted is a control output voltage level or higher. CONSTITUTION:A voltage level calculator 10 receives a detected power source voltage Vs, obtains a voltage level to be converted by a motor driver 2 with the voltage Vs level, and sends the voltage level to be converted to a comparator 11. The comparator 11 receives a control signal S from a control circuit 4, obtains a control output voltage level in the driver 2, and compares the control output level with the voltage level to be converted from the calculator 10. When the voltage level to be converted is higher than the control output level, even if the voltage Vs is lowered, the operation of a motor 5 is continued.

Title: Gas turbine rotor
Inventor: UMEZAWA SADAO
IPC: F01D5/06
Filed: 1980-12-12
Abstract: PURPOSE: To eliminate a slip among wheels of a gas turbine rotor composed of multiple wheels by alternately arranging binding bolts with the same coefficient of thermal expansion as that of the wheel and with the lower coefficient.  
     CONSTITUTION: 3 wheels 1 and a shaft 2 are bound tight by 8 bolts 3a and 8 bolts 3b alternately. A286, the same material as the wheel 1, is used for the bolt 3a, and heat resistant steel of Cr-Mo family with the lower coefficient of thermal expansion than A286 is used for the bolt 3b. The bolt 3a is bound as tight as possible within the extent that its binding stress does not exceed the permissible tensile stress σ u ,which is 0.5 times of its yield strength under a normal temperature and a non-operating condition. The bolt 3b is bound as tight as possible within the extent that its binding stress does not exceed σμ, estimating the shrinkage in the direction of the wheel axle caused by the wheel temperature and the centrifugal force under a normal operating condition. Accordingly, the average binding stress of both bolts never fall below the tensile stress σ 1  which does not generate a slip.

Abstract: PROBLEM TO BE SOLVED: To avoid malfunctioning and dropping accidents even if a slider is shortened and to make the relative positions of the slider, a wafer, and a torsion coil spring unlikely to vary by providing the wafer with a guide wall for positioning the outer peripheral surface of the slider. SOLUTION: A cylindrical guide wall 13a that positions the outer peripheral surface of a slider 16 is projected into a wafer 14. Degradation of reliability due to variations in the relative positions, etc., of the inside of a system which serves as an actuator and a movable member is thereby prevented, so an operating stroke is increased. Therefore, even if the slider 16 is set as a short one, it is not tilted or dropped off when falling. Also, a torsion coil spring 15 has, at the free end of a connection 15e extending in the form of an approximately U shape from its winding 15c, a second winding 15f approximately equal in diameter to the winding 15c, so the coil spring 15 is in no danger of being entangled and can be automatically fed into the wafer 14 without hindrance during assembly.
